The butterfly bush is a profusely flowering shrub. Its full aromatic blooms draw butterflies, bees and hummingbirds. When the plant does not bloom, usually the problem is due to plant location, water problems or pruning techniques.
Location
The butterfly bush grows quickly and needs open space in a sunny location with well-drained soil for best blooming.
Light
The butterfly bush needs at least six hours of sunlight a day. In shady conditions the plant does not get enough sunlight to produce full bloom clusters.
Water
The butterfly bush needs about an inch of water a week in the summer to bloom.
Pruning
The typical butterfly bush blooms on new growth. When the plant is not heavily pruned, new growth is sparse with few blooms.
Fertilizer
According to Clemson University, the butterfly bush benefits from a layer of mulch and moderate fertilization for flowering.
Deadheading
Pinch off spent blooms so the plant puts out blooms on new branch tips.
